T0 on whom it may concern.

Be it known that We, EDSON J. OATLIN and LOUIS I-I. KILBOURNE, citizensof the United States, residing at Wellsboro, in the county of Tioga andState of Pennsylvania, have invented certain new and useful Improvementsin Nut-Locks, of which the following is a specification.

Thisinvention relates to nut-l0cks,and particularly to a device forlocking railway-joint nuts to the fish-plates 'of railway-rails.

The invention consists in the novel con struction and arrangement ofparts, and resides, essentially, in a plate having one or more ofisetsor projections peculiarly formed therein and a nut plate or plateshaving an aperture through which the said projections extend. In allnut-locks of this character known to us the plates have a staple or pinand are without flanges. The staple or pin is not sufficient towithstand the strain, and the fiangeless ends have not sufficientbearing upon the nuts to keep them from turning when they become loose,for a slight loosening of the nuts will permit them to turn past saidends. It is to overcome these objections and disadvantages that ourinvention is designed.

In the accompanying drawings, forming part of this specification, Figure1 is a perspective View of a railway-joint wit-h our invention applied.Fig. 2 is a perspective view of the plate having the offset. Fig. 3 is aperspective view of the nut-plate. Fig. at is an enlarged verticalsection through the offset with the plates assembled and the keyremoved.

The same numeral references denote the same parts throughout the severalviews of the drawings.

The railway-rails 1 are of the ordinary form and have the usual boltholes for bolts 2, which extend through a common fish-plate 3. The plate4 has holes 5, through which the bolts 2 extend to receive the nuts 6and 7, and said plate has end flanges 0r nut-abutments 8 at right anglesto the front of the plate. Where four bolts are employed the plate 4.

haswa reduced rectangular offset or U-shaped projection 9 midway thelength of the plate and extending outward centrally from the front faceof said plate. The plate 4 is reduced in width at the point where theoffset occurs, and the ofiset is struck up or formed by bending the saidreduced portion outwardly from the plate. Thus two plate portions areformed, rigidly joined by the projection 9, the bolt-holes 2 being aboutintermediate the abutment-flanges 8 and the projection 9. These flanges8 lock the outer nuts 6 against rotation and fix the nuts (either squareor other shape) to the bolts.

The nut-locking plate 10 is provided with end flanges l1, projecting atright angles from the front face of the plate, and has a rectangularopening 12 to lit the projection 9. This plate 10 is held upon theprojection 9 by the spring-key 13, having shoulders to prevent itsdisplacement, and the flanges ll engage the nuts 7 and prevent theirturning or becoming loose.

In assembling the parts the nuts 6 are run up hard againstthefish-plate, the plate 4 is placed against the fish-plate with itsflanges engaging the nuts 6, and the nuts 7 are screwed up fast againstthe plate 4:. Then the plate 10 is hung on the projection 9, with itsflanges engaging the nuts 7, and the key is driven through theprotruding end of the projection to fix the plate 10 against the platel. It will be seen that the plate-flanges afford a considerable bearingfor the nuts, so that in case they become loose they are still heldagainst turning by the said flanges. It is obvious that one, two, ormore of the projections or offsets may be formed on the plate and thatfor each projection an apertured plate is provided. The plate having theprojection may be made of such thickness and strength as to warrant thedispensation of the fish-plate,and in joining beams or other structuralelements our two plates may be employed to great advantage.

What we claim as new, and desire to secure by Letters Patent, is
